LIGHTING FIXTURE.

Application filed April 23, 1925. Serial No. 25,196.

The present invention relates to lighting sheet metal fixtures so madethat they do not appear to be stamping's.

Many forms of lighting fixtures are made from brass, aluminum or whitemetal in the form of one ormore castings. Chandelier ,and ceilingfixtures when made'of these castings are frequently provided withgracefully shaped holes or apertures which provide ornamentation, breakup the surface into more or less distinct parts,iand facilitate thecarrying out of the ornamental scheme of the fixture. They also reducethe weight of the fixture and sometimes permit making it out of a numberof identical cast parts suitably assembled.

, Stamped fixtures as heretofore made have generally had a stamped panwith surface ornamentation only. In addition to the surfaceornamentation these, pans were provided in some cases with a cut outcenter to accommodate a, glass bowl. The common types of fixtures withthese stamped bodies have compared rather unfavorably withthe moreelaborate castvfixtures, because the same or equal artistic merit wasdifficult or impossible to attain by, stamping. The available designs,both as to shape and surface ornamentatioin-suitable for this typeoffixture,

have been used by so many manufacturers that they have becomecommonplace and it is more diflicult to produce anew and distinctivedesign. For-these, and other reasons, the tendency .in the, manufactureof high class fixtures has been more toward the cast fixture,notwithstanding the greater expense for materials, shipping and handlingcharges, and. the increased labor charges for making castings over thecost of a stamping operation. I I v The present invention contemplatesthe provision of a stamped sheet metal lighting fixture which may beprovided with holes or apertures which are drawn in such a mannor as togive the stamping the appearance of a casting. The invention alsocontemplates the 'provisionof a stamped fixture with what appears to bethick massive arms and an encircling ring such as are common infixtures. v 7 v Furthermore the invention contemplates the manufactureof a stamped fixture body which may beprovided with surface orna S1OWjing'one of the apertures;

mentation of the same type which would appear on cast parts whereby thecast parts, such as arms maybe attached to the stamped body without anyappreciable 'line of de markatio'n.v I a I The accompanying drawingsshow, for purposes of illustration, two of the many possible forms oflighting fixture bodies in which the present invention maybe embodied,together with views showing a typical "arrangement of steps in carryingout the'manufacture of the fixture body, it being understood that thedrawings are merely illustrative.

In these drawings:

Fig. '1 is an edge viewof the sheet metal blank, suitable for making alighting fix-' ture body; I I

-Fig.-2 is a fragmentary sectional view;

and Figure 3 is a fragmentary top plan view, these are two figuresshowing an initial step informing a plate into a lighting fixture body.d Fig, 4 is a fragmentary sectional view, and Figure 5 is a fragmentaryplan view inverted, these two figures showing a subsequent step in theformation of a lighting fixture body, rudimentary recess having now beenformed; f s

Figure 6-and7 are, views similar to Figures 4 and 5 respectively,showing the blank after a still later step in the stamping oper- 1Figure 11 is a sectional view taken through one ofthe holes inthefixture and looking towardthe periphery of the stamping;

FigurelZis a sectional, view showing the arm formed between two of theapertures; Figure 13 isan elevational view of a five light ceilingfixture using a the present stamped body, a portion of the fixture beingshownjin dotted lines. I In making lighting fixture bodies, according tothe present invention, one uses a. sheet metal blank 10 of appropriategage and shape, and subjects it to a number of stamping operations, sorelated that the material is gradually pressed or drawn into the desiredshape without thinning the material or 0 fill weakening it. During thelater steps. of the process the dies are such as to give the stampingits surface ornamentation. The drawings. show. a typical. arrangement.or layout of steps in the stamping. up of one. form of lighting fixturebody. The actual number of steps in any particular case will, of coursedepend upon the conditions which arise therein. A. central portion ofthe blank 10ispressed downwardly as indicated in l igures and 3 to formmore or less plate-shaped body 11. This initial step, is merely a.preliminary stepv and. may sometimes be omitted in i'i'iaking certainforms of lighting fixture bodies. I prefer,however, t i,"e.1i'i. ploythis initial step it makes it y to draw the materialexcessively I 1p.Figr es t and 5 show the blanl: after it has bcci subjected to one ormore additional stamping operations. Here it willbe noted that thebodynow assumes a more ornan'iental" shape than it did in the form shown inFigures 2 and 3.. surface of the stamping is more gracefully curved andthe formation of regularly spaced. recesses 12 and 13 are alreadystarted, which atthis stage are merely rudimen tary. The metal, is notdrawn into any sharp corners or at sharp angles. The periphery of thestamping is drawn upwardly asindicated at lfl: to initiate the formationof a deep rim.

Figures 6 and 7. show alater step in the process of forming the body toshape. As

hereshown, thedepressed or recessed, areas 12-and 13are deeper and theangles into which the stamping is drawn are more sharply defined. Therim 1 L is drawn deeper and triminedif necessary. The dies for thisstepmay. be such as "to initiate the formation of surface contour or.ornamentation. For example one may form ridges, valleys or other shapeswhich will later be come a foundation for the more intricate surfaceornamentation of the finished body. A few of the curves whichmight thusbe formed is indicated in these figures at 15, 1 6', 17' and 18.

ln Figures 8 and 9 the stamping is shown as it appears after one or moreadditional pressing operations have been performed on it. It will. benoted that the curves and anglesare sharper than they were in thepreceding stages in making the body, and that the outer edge oftliestamping is now. drawn upwardly as indicated in 14 to provide acomparatively deep side wall. The recesses 12 and 13 are well definedand their entire side walls are of substantial depth.

Figures 10,11 and 12. indicate a lighting fixture body on whichthestamping operations have been completed. Thesefigure s showing thatsurface ornamentation has been in'ipressed into a metal withconsidercasting.

able detail, it being understood; that no effort has been made to showin these drawings the minute details of surface ornamentation. actuallyused in a, commercial; fix: ture. a more detailed h i g o such alighting fixture part is to be found in De sign Pat ent 66,059 ofDecember 9, 1924:, grant-ed on an application filed by me June 27, 1924.

During the last steps. in the process, the bottoms of the recesses ordepressions are puiichedout to provide apertures 20, and the sidewallsof these depressions are forced into a position, such that the edges ofthe punched holes are invisible from underneath. This may convenientlybe done by. forming the punch to stretch the marginal; portion 21slightly. The material between the holes becomes channelashaped asindicated in Figure 12.

During the finishing operations, the upper edge of the rim of thes'tampin is preferably turned in as indicated at 22 Figures 101 and 11.This seems to provide more rigid stamping, as well as providing anoutside rim of even smooth appearance and having substantial depth tomake the stamping have the appearance of a castin The stamping may bemade up to have two, three, fouig five or more holes or apertures toprovide the desired number ofarms accordii'ig to the style and size of'fixtilre intended." They may have any desired surface ornamentation,which maybe applied to a stamping, or drawn into various shapes asdesired. 2

Figure 13 shows in full lines apart of the body and part of the arms ofafive light ceiling fixture. Here thebody 30 is provided with a number ofholes or apertures 31. three of which appear in this fig: me of thedrawings, the other two being hidde i. Between each of these apertures.31 will be found the channel shaped arms 32 above referred to, whichappear as cast arms. The upper peripheral portion 33 of the fixture bodymay be a plain cylindrical sun-face which appears like the outside of aSurface ornamentation may be impressed as desired, a suitable form beingindicated.

' In making up the fixture it is preferable to use a number of castarms, such as the arms 34,, which may be fastened to the lightingfixture body in the usual manner, such as by the use of screws threadedinto the arms through the back side of the lighting fixture body. Thesearms are clamped against the lighting fixture body between the apertures31, and adjacent the periphery of the fixture. They are preferablyproyided with surface ornamentation of'th'e type suitable for castlighting fixture arms and are preferably given such shape and styleofornamentation'that they fit the stamped inc body very closely and theornamentation on the arms merges into the ornamentation on the body. 7

For example,,the arm shown in Design Patent 66,174, granted Dec. 9,1924, may be used with a body such as shown in Design- Patent 66,059,above referred to, to produce a fixture such as shown in Design Patent66,173, granted Dec. 9, 1924. In this way an illusion of the castfixture body with integral arms, is carried out. i

In this figure the lower part of the spindle for the fixture is shown at35' in full lines while the other parts of the fixture is shown indotted lines. A canopy is shown at 36 on the outer portion of the armsas indicated at 3st, the sockets at 37, the bobeches 38, the lamps at39, and the tassel at 40.

It is obvious that the invention may be embodied in many forms andconstructions, and I wish it to be understood the particular forms shownare but a few of the many forms. Various modifications and changes beingpossible, I do not limit myself in any way with respect thereto.
